In a recent article on mood-induction procedures, Clark (1983) concluded that the Velten Mood Induction Procedure (VMIP; Velten, 1968) produces a good analog state of mild, naturally occurring, retarded depression that is not explicable in terms of experimental demand characteristics. Clark concluded, however, that it is erroneous to view the relative success of the VMIP in simulating the effects of depression as support for cognitive theories of depression. While we agree with the first of Clark's conclusions, we disagree with his second conclusion that the VMIP is not a cognitive manipulation. The purpose of the present article is to argue that his ideas regarding the impact of the VMIP on mood and behavior are not supported by the existing data. Therefore, the VMIP results can be used to support Beck's (1976) cognitive theory of depression.  相似文献

In a recent article (Clark, 1983), I concluded that it is invalid to use the success of the Velten Mood Induction Procedure as evidence for cognitive theories of depression. Riskind and Rholes (1985) challenge this conclusion. Their arguments are discussed and critically evaluated.  相似文献

Although the concept of interpersonal pursuing and distancing has been introduced and used clinically, the lack of a reliable and valid measure has deterred its more formal investigation and relevance to personality theory. The Pursuing-Distancing (P-D) Scale, a 92-item measure of the behavioral expression of these characteristics, was developed. Evidence for internal consistency as well as internal support of construct validity is presented and discussed. An 80-item revised scale is available from the authors and is currently being evaluated in a variety of external validation settings.  相似文献

This was a study of the differences among individuals on their performance on oral and written versions of the Washington University Sentence Completion Test of ego development. The study included 192 subjects from three age groups: College age, community residents, and retired people. No oral versus written differences were found in scores. Gender was the only factor to exhibit a consistently significant effect on Sentence Completion Test score differences.  相似文献

In traumatized patients, Rorschach responses draw from a variety of sources, including the traumatic event itself, past and current experiences, and internal fantasy. As complex and highly condensed mental constructions, these responses often serve to reveal the meaning of the trauma in terms of the patient's prevailing personality conflicts. In many cases, this meaning may be hidden in the response's distortion of or elaboration on images drawn from the actual event.  相似文献

A social dilemma (Dawes, 1980) may be defined as a situation in which a collection of individuals is faced with a conflict between maximizing selfish interests and maximizing collective interests. The dilemma is based on the fact that if all choose to maximize selfish interests, all are worse off than if all choose to maximize collective interests. In a decomposed social dilemma (Pruitt, 1967), the outcomes are divided into two components: one component is based on one's own choice and the second component is based on the choices made by the others. Using 3-person decomposed games, two types of incentives were contrasted: a positive incentive (bonus) for cooperative choices and a negative incentive (penalty) for noncooperative choices. Two experiments were conducted using male college students. The results of both experiments showed that the positive incentive evoked a higher level of cooperation than the negative incentive. The results are discussed in terms of nonadditive utility components, Pruitt's motivational interpretation, and Kelley and Thibaut's (1978) theory of interdependence.  相似文献

One of the central hypotheses of learned helplessness theory is that exposure to noncontingency produces a reduced ability to perceive response-outcome relations (the postulated "cognitive deficit"). To test this hypothesis, subjects were exposed to a typical helplessness induction task and then asked to make judgments of the amount of control their responses exerted over a designated outcome (the onset of a light). Support for the postulated cognitive deficit would be found if subjects who experienced the induction underestimated the relation between their responses and outcomes. The results, however, demonstrated that induction subjects (n = 30) made higher and more accurate judgments of control than subjects in a no-treatment control group (n = 30). This finding clearly fails to support the postulated cognitive deficit and highlights the need for other direct tests of the basic hypotheses of helplessness theory.  相似文献
